How does system assign the number at the end of ttyUSB devices when multiple devices present upon system boots? #usb #serialport
I am trying to interface with multiple USB serial devices through c programming. The goal is to keep track of all physical devices across multiple power cycles and system cold start. The serial num...
Watching YouTube over #dialup via 12 modems is bonkers!

Does anyone put there have a recommendation for a USB->25 pin serial port cable?
Specifically I have a Stag PP39 EPROM burner which works fine with a DOS program and I want to be able to use it with Linux and the only physical port on the Stag is a 25 pin serial port.
TIA.
For those of you old enough to remember dial up internet connectivity with modems over analog telephone lines, then this episode of 'The Serial Port' might be of interest:
They investigate Multilink-PPP to see what speed improvements are possible when multiple individual analog modems connection are combined into one overall connection.
They then attempt to see how many simultaneous PPP sessions over multiple modems are possible and what speeds might be achieved! There appears to be no documentation on the upper limit for Multilink-PPP.
Can they stream YouTube 144p or 240p video over an analog connection? ๐ค๐คทโโ๏ธ
Earlier episodes cover the telecoms hardware in more detail so don't miss those if that detail floats your boat ๐๐

I've been trying to get my SA818 to play nice with an Arduino, and I think I finally got it. Turns out the SoftwareSerial library was causing problems when I tried to control the SA818. I wanted two ports so I could use the USB serial port for debugging, but alas, I had to do debugging a different way (got some LEDs and just flashed them in different patterns).
@wyatt Do I have this straight?
- DE-9 is the common connector for PC serial ports since the PC-AT, specified in TIA-574
- DB-9 is the connector on older RS-232 serial cards: a DB-25 subset with only the 9 pins commonly used by a serial port
